In order to build wind turbines and electric cars, we need tons of magnets. Currently, we import these mainly from China, which means Europe is very dependent on this superpower for the energy transition. This has to change, according to industrial ecologist René Kleijn. In the REEsilience project,…

We find ourselves in an era of transition, not just towards a more computing- and data-driven society but also away from unsustainable fossil fuels as an energy source.

Electrolysis is a technique that can be used to convert CO2 into fuels and other useful products. To do this efficiently and on a large scale, however, we need to understand exactly how electrolysis works. Professor Marc Koper is an expert in this field.

Commercial enterprises who want to make use of the expertise and facilities are referred to LAB , the commercial unit responsible for specialized laboratory work.

What are the key issues in conducting LCA of bioenergy systems? What is the environmental sustainability status of second generation bioethanol? How much would the final results of biogenic carbon neutrality assumptions deviate from the true values based on a complete inventory? How to assess the impact…

Leiden University will be recording a brand-new series of podcasts in 2019: Science Shots. Our top scientists will talk about their research in less than 15 minutes. Tip: something to enjoy on the train journey between Leiden and The Hague, our two University cities!

An effective and equitable approach to resource conflicts?

For three millennia, carved sculptures were ubiquitous among ancient peoples in the Americas. Sculpted in stone, metal or wood, they developed into the well-known totem poles, colossal Olmec heads, royal Maya stelae and golden Inca statues.

How to get involved in sustainability? Read more about four projects that Leiden University helped realise in the past few years.

An interdisciplinary and innovative research group combining History, underwater archaeology, GIS and wood provenancing methods.

The chemical industry must continue to innovate for a more sustainable, healthier society. The reseachers from the Leiden Institute of Chemistry (LIC) contribute by applying their knowledge to themes such as sustainability, energy and health.

n this PhD thesis, the recombination of different atomic lattices in stacked 2D materials such as twisted bilayer graphene is studied. Using the different possibilities of Low-Energy Electron Microscopy (LEEM), the domain forming between the two atomic layers with small differences is studied.

This project examines the notion of sacred fertility and sacred landscapes, associated rituals and material culture, both archaeological and ethnographic manifestations in the Horn of Africa.

In the current global context, there is a pressing need to address sustainable energy supplies to safeguard our Planet and its ecosystems. The choices made by human society have a significant impact on genetic evolution and climate.

How can the Safe and Sustainable by Design (SSbD) framework developed in the SSbD4CheM project facilitate the creation of safer and more sustainable chemicals and materials across various industries?

The aim of the project is the development of polypept(o)ide-based delivery systems to use siRNA as systemic applicated therapeutic agent against e.g. solid tumors

How can we organise society so as to keep our planet habitable for us and for all other life forms around us? To answer this question, Leiden researchers collaborate across disciplines, from biology to data science, and from environmental economy to archaeology.

In the beginning of December 2016 PhD candidate Catarina Guzzo Falci was awarded a scholarship for a collections study by Musée du quai Branly. The Musée du quai Branly has implemented this scholarship programme to document its collections.

Lecture, Histories Connected: Work-in-Progress

This dissertation provides a grammatical description of the Awjila language, a small Berber language spoken in the Libyan oasis of Awjila.

What are the critical elements in sonic materialization of fixed media electroacoustic music and how can these parameters be classified? How would interpretation be defined in performing fixed media music? What are the creative and new ways of presenting fixed media music by incorporating all the presentation…

The work in this thesis demonstrates how to obtain an atomic-scale picture of a diverse set of complex surface structures observed using STM, under disparate conditions.

The energy transition ranks high on the European policy agenda, but what does it take to get there? René Kleijn researches how we can extract, use and reuse raw materials in a responsible way. Since 1 March, he has been appointed professor of Resilient resource supply.

Reuse everything and stop producing waste. By 2050, the Netherlands should have a circular economy. However, the new Integral Circular Economy Report by the Netherlands Environmental Assessment Agency (PBL) shows that there is still a long way to go. For the report, the Institute of Environmental Sciences…

Unravelling networks of human mobility and exchange of goods and ideas from a pre-colonial, pan-Caribbean perspective

This research project problematizes the applicability of ballet within a contemporary choreographic practice.

Embracing the Provinces is a collection of essays focused on people and their daily lives living in the Roman provinces, c. 27 BC-AD 476. It offers an overview of current research on Roman provinces and frontiers, deconstructing some long-held preconceptions and providing refreshing insights into unexplored…

What does the excavated material tell us about the continuation and/or change of urban life during the transitional phrases from Antiquity to the Middle Ages on Crete and in the eastern Mediterranean more generally?

Integrating life cycle assessment (LCA) with life cycle costing (LCC) offers the opportunity to simultaneously analyze the environmental and economic aspects of product alternatives, for the integration of which a unified computational has been proposed by Heijungs et al. (2013) [1]. The project aims…

Natural resources are becoming increasingly scarce. If we want to maintain our current standard of living, we will need inventive solutions. The researchers at the Institute of Environmental Sciences (CML) share their thoughts on how to achieve a fully circular economy in which as little use as possible…

PRINCE (for Policy Relevant Indicators for Consumption and Environment) was a three-year project set up to explore ways to improve and expand the set of indicators used to estimate the environmental impacts linked to Swedish consumption, both within Sweden and abroad. Any new methods and indicators…

The current migration flow into Europa demands effective measures. Leiden experts examine whether these measures are legal and hold up a mirror to policy-makers.

Urbanization brings benefits like housing and jobs but also challenges like biodiversity loss. CML's Urban research program uses science to create sustainable cities, focusing on the built environment (circular economy, urban mining) and enhancing urban nature for biodiversity and human benefits.

The car we buy is made out of thousands of components, which are produced using different types of materials. These materials need to be sourced from different places, sent to production facilities and assembled. Once the car is dismissed, the components need to be taken care of by either reusing, recycling…
